Introduction
In the previous tutorial, we have seen how to create an user and how to generate a diet for them. If you haven’t done it, check it out here. Let’s say that we want to configure the diets to be according to the user’s taste. How do we do this? Or maybe the user has some allergies and they would prefer to avoid some ingredients. The good news is that CraveAPI offers support for customizing diets!
Diet configuration
There are two ways in which you can control how the diet will look like:
- An API call which you can use to set the ingredients that the user does not want in his diet.
Here we have an example of a request that tells the Crave algorithm that the user does not want an ingredient at all.
Code
const userId = "62ab2382c1767a00de5b03ce";
const ingredientId = "62ab1050c1767a00de5b03bc";
const options = {
method: 'PUT',
url: 'https://crave-api.p.rapidapi.com/user/${userId}/ingredients/excluded',
headers: {
'content-type': 'application/json',
'accept-language': 'ro',
'X-RapidAPI-Key': apiKey,
'X-RapidAPI-Host': 'crave-api.p.rapidapi.com'
},
data: {
"ingredientIds": [ingredientId]
}
};
const response = await axios.request(options);
The body of the request is a JSON that contains an array with the list of ingredients that are less desirable for the user with id userId. In our example, there is only one ingredient. The list of ingredients from which to pick can be retrieved by making the GET call to route /ingredients.
Let’s also add a command to get the list of ingredients.
Code
else if (command === "getIngredients") {
const options = {
method: 'GET',
url: 'https://crave-api.p.rapidapi.com/ingredients',
headers: {
'accept-language': 'en',
'X-RapidAPI-Key': apiKey,
'X-RapidAPI-Host': 'crave-api.p.rapidapi.com'
}
};
axios.request(options).then(function (response) {
response.data.forEach((foodCategory) => {
console.log(`${foodCategory.name}:`);
foodCategory.ingredients.forEach((ingredient) => {
console.log(` [${ingredient.id}]: ${ingredient.name}`);
});
});
}).catch(function (error) {
console.error(error);
});
}
This command will list all the ingredients available in the CraveAPI database together with their identifiers.
- The second option to customize a diet is an API call that can be used to replace an ingredient from an existing diet. However, an ingredient that exists in an existing diet can not be replaced with any other ingredient. First you have to make a call to retrieve the list of ingredients from which you can pick one that will replace the unwanted ingredient.
Code
const options = {
method: 'GET',
url: 'https://crave-api.p.rapidapi.com/user/${userId}/diet/${dayIndex}/${mealType}/${ingredientId}/replace',
headers: {
'accept-language': 'ro',
'X-RapidAPI-Key': apiKey,
'X-RapidAPI-Host': 'crave-api.p.rapidapi.com'
}
};
const response = await axios.request(options);
You have to pass in the URL the user’s id, the day’s index, the type of meal (e.g.: breakfast, snack, dinner) and the id of the ingredient that we want to replace.
Once we have the id of the ingredients, we can pick one and make the request.
Code
const options = {
method: 'PUT',
url: 'https://crave-api.p.rapidapi.com/user/${userId}/diet/${dayIndex}/${mealType}/${toBeReplacedIngredientId}/replace',
headers: {
'content-type': 'application/json',
'X-RapidAPI-Key': apiKey,
'X-RapidAPI-Host': 'crave-api.p.rapidapi.com'
},
data: '{"ingredientId": newIngredientId}'
};
axios.request(options).then(function (response) {
console.log(response.data);
}).catch(function (error) {
console.error(error);
});
How to test it
Firstly, we set the ingredients that our users does not want to have in their diet. The user first have to get the list of ingredients and to do this they have to run:
node index.js getIngredients
Vegetables:
[616eca55953bf31b472e0e39]: Arugula
[616eca55953bf31b472e0e3a]: Asian Stir-fry vegetables
[616eca56953bf31b472e0e3b]: Mixed grilled vegetables
...
From this list, the user will select the undesirable ingredients.
node index.js setExcludedIngredients 62af3a0fc1767a00de5b03cf 616eca8c953bf31b472e0ef9 616eca8d953bf31b472e0efe
The excluded ingredients are:
[616eca8c953bf31b472e0ef9]: Cereals, Quinoa, rice and spinach mix, frozen
[616eca8d953bf31b472e0efe]: Cereals, Rye flakes
Now, the diet can be generated.
node index.js generateDiet 62af3a0fc1767a00de5b03cf 616ec98827b0e601644583df 70 2
